I want to draw multiple constant lines in a figure. I coded below using xline() and yline() refering Vertical line with constant x-value - MATLAB xline (mathworks.com). But it doesn't work. Would you tell me what is wrong?
xline([1,2,3]);

Has the ability to include multiple lines changed from Matlab 2020b to 2021a?
I get "Passing multiple values to ConstantLine is not supported." when I try to include multiple x-coordinates to xline.
I'm able to do it in 2021b.

Yes. The ability to include a vector of inputs to xline and yline was added in R2021a.
See the corresponding release notes.

When I code like this
clear;
xline([1,2,3]);
error happen.
Error using xline (line 29)
Passing multiple values to ConstantLine is not supported.
Error in test (line 2)
xline([1,2,3]);
I am using R2020b now. Should I install R2021a?

It works in R2021a, as you can see. What version of MATLAB are you using?

I'm using R2020b version: 9.9.0.1592791 Update 5.
I'm going to install R2021a and try it. Thank you.
